Using the [UP], [DOWN] and [DIGIT] soft-keys, enter the true local barometric pressure. This
corresponds to a reading from a mercury barometer. Do NOT use the pressure reported by the
weather bureau. Weather bureaus correct pressures to sea level.
NOTE: You may estimate the standard pressure at your altitude by using Appendix B - Pressures
and Altitudes.
Press [ENTER] to confirm. The message “PRESSURE CALIBRATION SAVED” will be displayed, on
the model 5100, as shown below. The model 5000 will display “PRESSURE SETTING SAVED” ,
since it does not contain an internal barometer.

NOTE: If you wish to abort before pressing [ENTER], you may press [MODE] to return to the
calibrate menu without saving the new value for barometric pressure. You may also press
[NEXT] to select a different parameter (any change made will not be saved).
Salinity
Salt reduces the ability of water to hold oxygen in solution. Enter the salinity of the sample you
are measuring and the meter will automatically compensate for the effect of salinity on dissolved
oxygen. The default setting for salinity is 0.0 ppt. You can enter any value between 0.0 and 40.0
ppt.
From the Calibration menu press the [DO CAL] soft-key, then press the [NEXT] soft-key until
the salinity value is flashing. The top right corner of the screen will display “Salinity” as shown
in the following screen. Remember, if you are manually calibrating in mg/L in water saturated
air, salinity is 0.0 ppt.
